I'm sorry I'm not being clear it seems. I'm talking about famous devices. Mainstream ones, get it?

Tell me a touchscreen phone that has been severely popular before the iPhone!

A PDA, was just right that: PDA. People would look at it as a small computer, not an easy cell phone they could use like the iPhone back in the time. Later when they were merged with cell phones it made a little slapsh, but the true touchscreen fever came with the iPhone.

if you have an opinion different than this, please do not insult others with a "riiight... lol".

That's provocative and an insult, imo.

Last year, Japanese wireless carrier KDDI started selling the first commercially available 3-D cellphone, called the Hitachi Woo. More than 300,000 devices were sold in in just a few weeks. The Woo’s 3-D display, powered by masterImage, uses a parallax barrier, a layer that’s placed over an LCD screen to help produce the feeling of depth by directing slightly different images to each eye.

“We can create a 3-D experience in pretty much any kind of screen including LCD and OLED,” says Bowers.

3-D films such as Avatar and Alice in Wonderland have sparked consumer interest in the format. Most major TV makers including Sony, LG, Panasonic and Mitsubishi have started selling 3-D TVs. ESPN launched a 3-D channel in time for the football World Cup. Even PC makers have hopped on to the trend with the launch of computers with 3-D displays.

“One hundred percent of handset manufacturers are evaluating 3-D behind the scenes,” says James Bower, president of MasterImage 3-D, a Burbank, California, company that makes 3-D displays. “Everyone wants a glasses-free 3-D experience.

MasterImage’s 3-D technology that’s used in the Woo is similar to what display maker Sharp has created for Nintendo’s 3DS Portable. Both use the concept of a parallax barrier.

A layer of material with a number of small, precise slits is placed on top of a display. The slits direct light from each image slightly differently creating a “sweet spot” that can range from 12 inches to 20 inches in front of the screen. At the sweet spot, the brain sees two slightly offset images that it can use to create a composite with the perception of depth. MasterImage says the 3-D layer adds about $10 to $15 to the overall bill of materials for the phone.

“Only one person who’s holding the phone can see the 3-D effect,” says Bowers, “but we have created a good sweet spot so there’s no struggling to find the the right position.”

That doesn’t mean the results are perfect, but it’s good enough to experience 3-D without requiring cumbersome glasses or extremely sophisticated technology.

But the ease of use comes at a price. Adding a layer on top of the LCD or OLED screen reduces brightness by up to 50 percent and resolution by almost the same number.

Bowers says the additional information that the brain perceives because of depth helps make up for some of that.

“Technically you are losing resolution but psychologically you are gaining a lot more information,” he says.

im sorry but you seem to imply that Nintendo is the one making 3D popular all by their lonesome, an you call riiight as insulting. also for your comment about touchscreen's before the Iphone that were popular what about palm treo's quite popular and had touchscreen's

and HTC winmo 5.0 an 6 based phones sold million's of phones all touch screen.

you keep saying that with touch screen's that up to the iphone there ware no mainstream popular touchscreen phone's..and that is just bunk and you know it. so please stop.

I kindly disagree with your opinion pal. There was nothing comparable to the iPhone's success on the touchscreen market before it's arrival, and I'm talking about the world, and the world isn't just the USA as some people think. We're not getting anywhere with our discussion and we've created enough off topic already. so please stop.

And for the Hitachi Wooo numbers. It sold 300,000 in a "few weeks". 3DS will do that in the first 24 hours... Only in the USA. That's a mainstream achievement.

yes and so what if they do..it's quite impressive, for a single device but hardly impressive vs every other 3D screen enabled smartphone that will also be in the market.

the 3DS is not an island all unto it's self. just like the Iphone was not also. as for popularity there was quite a number of TREO'S SOLD ESP THE 650 MODEL LONG BEFORE THE Iphone made it to the market.

already Take Android already there are more Devices with the Android OS than there is total number of iphone's and Ipads combined in the world . I am not saying that the 3DS number of sales would not be impressive i am pretty sure they will be. I am just not going to agree with the Idea that you have about Nintendo is the only one that is going to make 3D mainstream, yes they will help. but they will be far from alone.
